Amiodarone Treatment

Abstract Amiodarone-induced thyrotoxicosis (AIT) is a well-known complication of amiodarone treatment found in 3% to 12% of patients. Two types of AIT have been described, each associated with a distinct histologic pattern of thyroid involvement. Type 1, which typically develops in the background of pre-existing thyroid disease, is due to iodine-induced excess thyroid hormone synthesis, whereas type 2 is due to destructive thyroiditis. The prevalence of thyroid cancer in patients with AIT is unknown. We report a case of papillary thyroid carcinoma associated with type 2 AIT.

Lipid Spectrum

Despite the fact that most young patients with hyperglycemia are diagnosed with type 1 (T1DM) and type 2 (T2DM) diabetes, up to 10 % of all cases of the disease are MODY diabetes. The most common types of MODY are GCK-MODY and HNF1A-MODY, therefore the investigation of their clinical and laboratory characteristics, including lipid spectrum indicators is of high clinical significance. The aim of this research work was to study the values of lipid spectrum indicators in patients diagnosed with GCK-MODY and HNF1A-MODY at the age from 18 to 45 years. Lipid profile parameters were investigated in 56 patients aged 18 to 45 years with diagnosed GCK-MODY and HNF1A-MODY by molecular genetic tests, matched by sex, age and body mass index (BMI). No statistically significant differences were found for any of the indicators, however, in patients with HNF1A-MODY, the decrease in HDL-C is determined significantly more often than in GCKMODY. Thus, the group of persons with MODY differs in the level of lipid profile indices depending on the type of MODY.

Since the autoimmune nature of type 1 diabetes mellitus came to become known some 40 years ago, continuous investigations have been carried out in an attempt to improve approaches to prognostication of this disease and develop new safe and efficacious methods for its prevention. For all that, many aspects of diabetes pathogenesis still remain far from clear. In most cases (roughly 85%), type 1 diabetes mellitus (DM1) develops sporadically in the absence of a relevant familial or hereditary history of this condition. Accordingly, the first-degree relatives account for only 15% of all DM1 patients. The risk of development of DM1 in the Russian population estimated by the researchers of the Children' Department, Endocrinological Research Centre, is relatively low (0.2%). It depends on many factors, such as the number of ill and healthy relatives, the chronological age of a given patient and the age of onset of clinical manifestations in his (her) relatives. Type 1 diabetes-predisposing and protective haplotypes were identified in the Russian population based on the results of molecular-genetic studies involving 599 children and adolescents with DM1. These and immunological data were used to distinguish between risk groups in the families of diabetic patients and the rationale was proposed for the dynamic follow-up of these subjects. It is concluded that estimation of the risk of type 1 diabetes mellitus based on the results of molecular-genetic studies and monitoring immunological markers constitutes the first step in the elaboration of preventive measures designed to prevent or delay the development of the disease.

Publically available (own) transcriptomic data were re-analyzed to quantify the alteration of functional pathways in the thyroid cancer, establish the gene hierarchy, identify potential gene targets and predict the effects of their manipulation. The expression data were generated from one case of papillary thyroid carcinoma (PTC) and from genetically manipulated BCPAP (papillary) and 8505C (anaplastic) human thyroid cancer cell lines. The study used the genomic fabric perspective that considers the transcriptome as a multi-dimensional mathematical object based on the three independent characteristics that can be derived for each gene from the expression data. We found remarkable remodeling of the thyroid hormone synthesis, cell cycle, oxidative phosphorylation and apoptosis pathways. Serine peptidase inhibitor, Kunitz type, 2 (SPINT2) was identified as the Gene Master Regulator of the investigated PTC. The substantial increase of the expression synergism of SPINT2 with apoptosis genes in the cancer nodule with respect to the surrounding normal tissue (NOR) suggests that its experimental overexpression may force the PTC cells into apoptosis with negligible effect on the NOR cells. The predictive value of the expression coordination for the expression regulation was validated with data from 8505C and BCPAP cells before and after lentiviral transfection with DDX19B.

Introduction. In the last decade several population studies on the association of the genes NKX2-1 and FOXE1 with sporadic papillary thyroid cancer were conducted. In the Kazakh population of similar work to date were not conducted. The aim of this study was to study the genetic association of the FOXE1 (rs9655313) and NKX2-1 (rs944289) oncomarkers with papillary thyroid cancer in the Kazakh population. Materials and methods. We conducted a case-control study that allows us to retrospectively evaluate the association of NKX2-1 and FOXE1 genes and papillary thyroid cancer. Results. The frequency distribution of FOXE1 rs965513 polymorphism in the group of papillary thyroid cancer and the control group detected by healthy individuals was significantly different (χ2 = 100.09, D.f. = 2, p = 0.000). In the group of cases, the AA genotype (17.5%) was in three times more often compared with the control group (5.1%). The GG variant had a lower frequency in the group of persons of papillary thyroid cancer (37.9%) against the control group (61.4%), the odds ratio (OR) in the FOXE1 rs965513 group was 2.367. The distribution of the NKX2-1 (rs944289) polymorphism frequencies in the compared groups of values were significantly different (χ2 = 100.09, D.f. = 2, p = 0.000). In the group of cases, the genotype of TT (30.5%) against the control group (20.7%) was 1.5 times more common. The SS variant had a lower frequency of occurrence in the group of persons of papillary thyroid cancer (19.8%) against the control group (28.9%), OR in NKX2-1 (rs944289) group was 1.46. Conclusion. Carrying out screening for carriers of FOXE1 rs965513 and NKX2-1 (rs944289) can become an effective means of early diagnosis with a high frequency of its spread and associations with cases of papillary thyroid cancer in the Kazakh population.

Review Of The Literature

We present a case of Warthin-like papillary thyroid carcinoma in a 22-year-old woman and a review of the literature on the topic. The patient had the occasional discovery of a hypoechoic thyroid nodule of approximately 18 mm, characterized by irregular margins, hyperechoic spots, rich intra- and perilesional vascularization, and a suspicious enlarged right laterocervical lymph node. Fine-needle aspiration was performed for both lesions and the diagnosis of papillary thyroid carcinoma without lymph node involvement was made. The patient underwent thyroidectomy and central neck lymphadenectomy without complications. Histopathological examination suggested a Warthin-like papillary carcinoma of the thyroid gland, with all the removed lymph nodes being free of disease. The patient subsequently underwent iodine ablative therapy and she remains free of disease one year after surgery. Warthin-like papillary thyroid carcinoma is a recently described variant of papillary thyroid cancer that is frequently associated with lymphocytic thyroiditis. Morphologically, it resembles Warthin tumors of the salivary glands, with T and B lymphocytes infiltrating the stalks of papillae lined with oncocytic cells. Surgical and postoperative management is identical to that of classic differentiated thyroid cancer, while prognosis seems to be favourable.
